0.076 mol of the compound obtained in Step C is introduced in a 500 ml round-bottomed flask, and then 250 ml of water and 0.152 mol of NaOH are added. The reaction mixture is stirred for 12 hours at ambient temperature. The reaction mixture is then acidified with 3M HCl and is extracted twice with ethyl ether. The organic phase is dried over MgSO4 and evaporated under reduced pressure to obtain the title product in the form of a white solid.
